Generally, you can transmit items to a TI
-
83 from a TI
-
82,
but differences between the two products may affect some
transmitted data. This table shows differences for which
the software built into the TI
-
83 automatically adjusts
when a TI
-
83 receives TI
-
82 data.

For example, if you transmit from a TI
-
82 to a TI
-
83 a
program that contains
n
Start
on a command line and then
display the program on the receiving TI
-
83, you will see
that
n
Min
has automatically replaced
n
Start
on the
command line.
The software built into the TI
-
83 cannot resolve some
differences between the TI
-
82 and TI
-
83, which are
described below. You must edit the data on the TI
-
83 after
you transmit to account for these differences, or the TI
-
83
will misinterpret the data.
The TI
-
83 reinterprets TI
-
82 prefix functions to include
open parentheses, which may add extraneous parentheses
to transmitted expressions.
For example, if you transmit
sin X+5
from a TI
-
82 to a
TI
.
83, the TI
-
83 reinterprets it as
sin(X+5
. Without a closing
parenthesis after
X
, the TI
-
83 interprets this as
sin(X+5)
, not
the sum of
5
and
sin(X)
.
If a TI
-
82 instruction that the TI
-
83 cannot translate is
transmitted, the
ERR:INVALID
menu is displayed when the
TI
-
83 attempts to execute the instruction. For example, on
the TI
-
82, the character group
U
n-1
is pasted to the cursor
location when you press
y
[
Un
N
1
]. The TI
-
83 cannot
directly translate
U
n-1
to the TI
-
83 syntax
u(n
N
1)
, so the
ERR:INVALID
menu is displayed.
Note:
TI
-
83 implied multiplication rules differ from those of the TI
.
82.
For example, the TI
-
83 evaluates
1
à
2X
as
(1
à
2)
ä
X
, while the TI
-
82
evaluates
1
à
2X
as
1
à
(2
ä
X)
(Chapter 2).
